[Cross section of notebook personal computer]
Here, a structure in which the battery unit 42 is fixed to the bottom surface of the main body 21 with screws 43 and 44 will be described with reference to FIG.

  FIG. 4 is a front sectional view of the main body 21 of the personal computer 11 in the vicinity of the screw 43 that fixes the battery unit 42.

  As shown in FIG. 4, a palm rest support portion 51 for supporting the palm rest 25 with respect to the bottom 41 is joined to the inner wall surface of the palm rest 25. The palm rest support portion 51 is provided with a cylindrical portion 51 a for screwing with the screw 43. In order for the screw 43 and the cylindrical portion 51a to be screwed together, an insert nut may be provided inside the cylindrical portion 51a, or the screw 43 may have a self-tapping screw function. Further, the bottom 41 and the battery unit 42 are each provided with a through hole for inserting the screw 43 at a position corresponding to the cylindrical portion 51a.

  That is, the screw 43 is inserted from the bottom surface side of the main body 21 through the through holes of the battery unit 42 and the bottom 41 and screwed with the cylindrical portion 51a of the palm rest support portion 51, whereby the palm rest support portion 51, the bottom 41, and The battery unit 42 is fastened together. In addition, in FIG. 4, although the palm rest support part 51 is comprised as a component different from the palm rest 25, you may be comprised as one component. In this case, the screw 43 fastens the palm rest 25, the bottom 41, and the battery unit 42 together.

  In the above description, the structure in which the screw 43 fixes the battery unit 42 has been described, but the structure of the screw 44 is the same.

  Generally, the battery unit 42 in which a battery cell having higher rigidity than that of a housing of an electronic device and an exterior member are integrally configured has higher rigidity than the palm rest 25 and the bottom 41 of the main body 21. Accordingly, the palm rest 25 (palm rest support portion 51), the bottom 41, and the battery unit 42 are fastened together with the screw 43 by the structure as described above, so that the rigidity of the main body 21 of the personal computer 11 can be increased. become.

  For example, in a conventional notebook personal computer with a reduced thickness, a recess for attaching a battery cell to a part of the bottom and a lid covering the recess are provided, and the battery is opened and closed by opening and closing the lid. The cell is designed to be attached and detached. In such a structure, a gap is generated between the battery cell and a space for accommodating the battery cell, which is configured by a recess and a lid provided at the bottom. The rigidity of the external force applied to one end in the left-right direction (longitudinal direction) of the main body of such a notebook personal computer is almost the same as the rigidity of the palm rest and the bottom due to the presence of the gap. It will be a thing. Therefore, when the user grips and lifts one end of the main body of the notebook personal computer in the left-right direction, the main body may bend and the user may be worried about handling the laptop personal computer. was there.

  Therefore, as shown in FIG. 3, the battery unit 42 is accommodated in the bottom 41 so that the left-right direction (longitudinal direction) of the main body 21 and the left-right direction (longitudinal direction) of the battery unit 42 are parallel, By adopting a structure in which the palm rest 25, the bottom 41, and the battery unit 42 are fastened together with the screws 43 and 44, the rigidity against an external force applied to one end in the left-right direction (longitudinal direction) of the main body 21 of the personal computer 11 is The rigidity of the unit 42 is substantially equivalent. Thereby, even when the user grips and lifts one end in the left-right direction of the main body 21 of the personal computer 11, the deflection generated in the main body can be suppressed, and the user is worried about handling the personal computer 11. Will be able to avoid.

  Returning to the description of FIG. 3, the personal computer 11 is placed on the installation surface of a desk or the like at the corner of the bottom 41 on the side where the recess for accommodating the battery unit 42 is not provided (arrow D direction side). Rubber feet 45-1 and 45-2, which are elastic members for ensuring the stability of the computer 11, are provided so as to protrude from the bottom surface of the main body 21.

  Further, the above-described screws 43-1 to 43-4 are configured such that their heads are made of an elastic member such as elastomer (rubber), and at least a part of the heads protrude from the bottom surface of the main body 21. The battery unit 42 is fixed to the bottom surface of the main body 21. That is, the screws 43-1 to 43-4 have the same functions as the rubber feet 45-1 and 45-2.

  As described above, the heads of the screws 43-1 to 43-4 are made of an elastic member, thereby reducing the number of parts when compared with a configuration in which the screws and the rubber feet are separately provided. be able to. Thereby, while being able to simplify the design of arrangement | positioning of the components in the bottom face of the main body 21 of the personal computer 11, the manufacturing man-hour and component cost of the personal computer 11 can be held down.

  In addition, the number of parts can be reduced even when compared with a configuration in which rubber feet are attached to the through holes of the battery unit 42 so as to cover the screws for fixing the battery unit 42. In this case, even if the design of the arrangement of components on the bottom surface of the main body 21 is the same, the manufacturing man-hours and component costs of the personal computer 11 can be suppressed.

[Structure of screw]
Here, a detailed configuration of the screw 43 will be described with reference to FIGS. 5 and 6. FIG. 5 is a perspective view of the screw 43, and FIG. 6 is a cross-sectional view of the screw 43 when cut along a plane including the rotation axis of the screw 43.

  The screw 43 includes a shaft portion 61 and a head portion 62.

  The shaft portion 61 is formed of a metal member, and a spiral groove for the screw 43 to function as a so-called male screw is provided on a side surface of the cylindrical portion. As described above, the spiral groove may be provided so that the screw 43 functions as a self-tapping screw. Note that the shaft portion 61 alone can function as a screw having a shaft portion and a head.

  As described above, the head portion 62 is made of an elastic member such as an elastomer (rubber), and is formed by integrating the head portion of the shaft portion 61 made of a metal member with the elastic member. Further, in the head 62, a surface parallel to the bottom surface of the main body 21 when the screw 43 is inserted into the main body 21 of the personal computer 11 (that is, the installation surface when the personal computer 11 is placed on the installation surface). A notch 62a is provided on the surface abutting on the surface. The notch 62 a is provided in the head 62 so as to pass through the rotation shaft of the screw 43. The width of the notch 62a is about one coin, and the bottom surface of the notch 62a as a groove is a gradual downward convex from both ends of the groove toward the center with respect to the length direction of the groove. It is shaped to draw a curve (arc).

  Further, a concave seat 62b is provided at the center of the bottom surface of the notch 62a, that is, at the intersection of the bottom surface of the notch 62a and the rotational axis of the screw 43.

  In the manufacturing process of the personal computer 11, when the screw 43 is inserted through the bottom surface of the main body 21, a dedicated electric driver having a tip portion that engages with the notch 62 a and the recessed seat 62 b of the head 62 is used. That is, the shape of the tip of this electric driver is approximately the thickness of one coin, and an arc corresponding to the groove of the notch 62a is drawn, and the tip end portion thereof (that is, the rotation of the shaft of the electric driver). A projection corresponding to the concave seat 62b is provided on the central portion). By engaging this protrusion with the concave seat 62b, the rotation center of the shaft of the electric driver and the rotation shaft of the screw 43 are on the same straight line, and the screw 43 can be inserted accurately.

  Although not shown in the drawing, the screw 44 is a screw that has a head portion made of the same metal member as the shaft portion, and that the head portion does not protrude from the bottom surface of the main body 21 as a result of joint fastening. Although the structure is different from that of the screw 43, a notch and a concave seat similar to those of the screw 43 are provided on the head thereof.

  Thus, since the width of the notch 62a of the head portion 62 of the screw 43 (and the screw 44) is about one coin, for example, the battery unit 42 needs to be replaced due to deterioration of the battery cell or the like. The user can easily loosen the screw 43 (or the screw 44) using one coin or the like without preparing a dedicated electric driver as described above. become.
